I dream of a new computer every day. I just can't do it. It's a struggle just to pay for gas and groceries right now. The refurbished macs are not even low enough for me.
Do you think i'll have a problem even upgrading to Yosemite? Here are a couple more screen shots that might help. One is from when I went to "About this Mac" and the other is from "get info" on my hard drive.
Thanks for your help!
